Answer:
it can occur in all waves because all wave have a frequency
The tennis ball that is hit the hardest would have the most kinetic energy.
Answer:
The answer for this question is 146 neutrons
I hope I can help! :)
A concave mirror is when the object is anywhere from infinity to focus the image so form will be real and inverted.
And when the object is between pole and focus of concave mirror then image so formed will be virtual and erect and the size of image is greater than size of object.
So, the answer would be "where light rays disperse."
Have a great day/evening/night! :)
Let me know if you have any additional questions!

Answer: 39.08664m
Normal free fall:
2s = 19.6133m/s
1s = 9.08665m/s
Assuming there's no air resistance:
The first second of the fall it will travel 15m
since the initial speed of the ball is 15m/s
this leaves us with 1 second, however by the time the ball ha traveled 1 second it will be accelerated by the force of gravity (9.08665)
15 + 9.08665 = 24.08665
We're already travelled 15m
and now 24.08665 will be covered in
the last second.
24.08665 + 15 = 39.08664m
-/
if we're gonna be technical:
a coins terminal velocity is only roughly around 19km/s so it wouldn't even travel much
(a brainliest would be appreciated)
